Figure 4. Type 2: Large Distributed Core Fabric Design

Each S4810 leaf for the Type 2: Large Distributed Core fabric design has the following:

• 40 Gb of fabric interlink (fabric links) maximum capacity to the spine (4x 10 Gb)

• 32 ports are used for fabric links (10 Gb) and 32 ports are used for the downlinks (10 Gb)

Type 3: Medium Distributed Core Fabric

With a Type 3: Medium Distributed Core design, the Z9000 spines (S6000 spines) connect to the S4810

leaves at a fixed 40 Gb line rate as shown in the following figure. The maximum number of leaves is

based on the maximum number of ports on the spine (for example, 32 ports for the Z9000). The

maximum number of spines is 16 and the maximum number of leaves is 32, as shown in the following

illustration. This illustration shows a networking system architecture in a data center as a distributed core

fabric containing a set of ToRs that connect to servers, storage devices, and network appliances (such as

load balancers or network security appliances). You can run application services, network services, and

network security services either on physical machines or virtual machines.
